APIEARA'I"[.J'S` FOR SECURING SHUTTERS IN ANY REQUIRED POSITION.

specification `ef Letters Patent No. 7,995, dated March 25, 1851.

To all whom t may concern Be it known that I, CHARLES, W.' KREBS, of Baltimore, `in the State of Maryland, have invented a new and Improved Mode of Holding Shutters; `and I do hereby declare that the following isla full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon. t

The nature of my invention consists in attaching to pintles secured near the inner edges ot the shutters two rods capable of being slid upon and in contact `with each other, each rod being provided with a socket and screw thereinwhich latter can be caused to enter into any one of a series of apertures formed in a flange secured to the shutter below the pintle above named.`

both screws to be worked on the same side of the arms; in the other end of each arm I make two sockets for each arm one socket lits the pivot of the hinge and is marked E, the other C is made a female screw, and lits the screw D which works into the holes of the flange A of the hinge, thereby holding the shutter in posit-ion, either shut orbowed x, The hinge or pintle has a` or open entirely. flange below it, perforated with a series of apertures into which the screw D is caused to enter, and prevents any motion of the shutter. This apparatus being properly adjusted to the shutters, will hold them in any desired position by the use of the screws, without being separated, and being4 clasped by a spring upon the outside blind, will keep them shut, s0 that they cannot be opened from without.

What claim isi t `The right to the rods, pintles, sockets, screws and apertures, connected, arranged, and acting substantially in the manner and for the purposes described.

CHARLES W. KREBS.
